To all-@hom it may concern: y

'Be it known that ll, AmNzo iB. Enr, a citizen of the United States ofAmerica', anda resident of Groton, county of Tompkins, and State of NewYork, have invented certain-new and useful llmprovementsI in .CushioningDevices (Case No. 173)', of which,

the following is a full and clear specificav tion.

This invention relates to improvements in cushioning devices and meansfor connecting the same with a support.

The invention has for one of its objects thev provision of a cushioningdevice and supporting means theretorso constructed that the cushioningdevice may be readily connected with and disconnected from the support.

Another object of the invention is to provide a cushioning device andsupporting means therefor so constructed thatthe cushionin device may besecurelyconnected with lts support without employing extraneousfastening devices.

Another object of the invention is to provide a cushioning device andsupport having af quick detachable interlocking slip connection. v

A further object of the invention is to provide a duplex reversiblecushioning device.

Stillanother object of 'the invention is to provide a reversibleresilient cushioning device having oppositely disposed dished portionsforming` suction gripping heads.

Tn the accompanying drawing,

Figure l is a .bottom plan View illustrating one embodiment of ltheinvention, in

which the cushioning device serves as a cushionor foot for the mainframe of a typewriting machine;

-orm of duplex or reversible per or cushion' and supporting meansthereforg adapted for use as. alsupporting toot for typewriters orother'devices, .oras abumper for moving parts out ty ewriting machines,

evices.

Referring to lt1`igs'..l,.2 and 3 of the drawings b numerals, thecushioning device is forme able or resilient material and has twooppositely :disposed cushioning portions. or-

heads 1 connected by a reduced -cy'lindrica'tl portion 2. The top andbottom faces of the ycushion `are dished or cupped, as shown at` ofrubber or other suitable yield- Y 3, to adapt either of the heads 1 toserve l l as a suction cup as well as a resilient cushion. The sides oteach head1 preferably curve inwardly, as shown, from the edge of thedished face thereof` to the contracted portion 2 to increase theeticiencyo 'the grippino` action of the suction cups thus formed.

T e duplex cushion may be connected to -variousarticles or machineframes such, for

example, as the main frame of a typewriting machine. TnllF-igs. l tor 3,T have shown the plate-like member or support l to which the cushion isattached as an integral en' tension of a horizontal flange 5 formed onthe preed steel main frame 6 of a Corona or other typewriting machine,one corner f portion only of the frame-being shown.

lfVhile-T have shown the supportfl. as being formed integrally withthemachine trame, it will be obvious thaty the support may' comprise aseparate plate fastened to the l frame in any suitable manner.

The'support 4r is formed with a circular aperture 7 of the same, orsubstantially the same, diameter `as 'the cylindrical shank portion 2 ofthe cushion, and said support is also formed with al throat or slotextending from one side ofthe aperture to the.

outer edge ot' the support. The inner end of the throat at its pointofconnection with the aperture 7 is of less width than the diameter ofthe aperture and 'the edlges 8 of the throat flare outwardly awayfromeach other toward the outer edge of the support, the outer end of thethroat being preferably as wide-as the diameter of the aperture 7.

Tt will be obviousy that/the Icushion. may be readily-connected to vanddisconnected from the machine frame by forcingthe con-- tracted shankportion 2.- laterally throu h slot' 8 into and out of aperture 7. T elinclined edges' 8 ot the throat serve. to gradually compress thecontracted portion 2 of the cushion and thus-increase the easel withwhich the cushion may be attached. As soon as the contracted portion ofthe cushion enters the aperture 7 it will expandA to its original form,lfilling said aperture, and thus be securely held to the frame Withoutthe necessity of employing screws, locking plates, or other extraneousfastening devices. lf one head of the cushion becomes Worn or damaged,thev cushion may be readily. detached and re-connected in re'-v versedposition. l

lin Fig. 4 a cushion or suction foot is shown, having a dished or cuppedportion 9, similar to the heads 1 of the duplex cushion above described,connected by a cylindrical contracted shank portion 10- with acylindrical portion or Vhead 11 having a flat outer face. l

In Fig. 5 a support 12, having an aperture and throat similar to theaperture 7 and throat 8 in the supportv 4, is shown. This support 12 maybe a part of a machine frame, as shown in Figs. 41,2 and 3, or may beattached' to or formed on various articles or machines', or parts ofmachine frames, to

' adapt the cushion carried thereby to serve asta supporting foot, abumper for a moving machine element, or the like. The duplex lreversiblebumper shown in this embodiment `of the invention has two cylindricalheads 13 connected by a reduced cylindrical shank portion 14 adapted tobe forced through the ythroat and expand in the aperture `in the.support.

While I have shown the heads of the cushioning device, and the reducedportion vor shank connecting said heads, as circular in cross sect1on,it will be obvious ythat the shape of either the heads or shank incrosssection may bevaried and that the shape of the aperture 7 may bevaried to conform with the shank portion 2. It will be obvious that theplate-like member to Which the cushion, suction, foot, orbumper isattached maybe of vaious shapes and may be formed on or connec ed invarious Ways to machine frames and articles of yvarious kinds. Theaperture and throat in the plate-like member form, in edect, a slot openat one end and closed at the other end and having a contracted' portionintermediate its ends. It will be observed also that the plate-likemember and the cushion, foot or bumper are so constructed as to have aquick detachable, interlocking, slip connection that permits attachmentofthe foot, bumper, or cushion toI to the plate with either head thereofat one side of .the plate.
